From active site dynamics to durable Ir-based aerogels: operando insights and a flash calcination strategy for the oxygen evolution reaction in proton exchange membrane water electrolysers

Year: 2026

Type: article

Abstract: Operando X-ray techniques reveal the instability of the IrCu aerogel arising from reversible oxide formation. A flash-calcination strategy enables successive surface passivation of the IrCu aerogel, resulting in an active and stable catalyst.
